Delhi saw slight relief from pollution on Monday as strong northwesterly winds pushed the city’s air quality into the ‘poor’ category after 24 days of ‘very poor’ levels.

Cyclone Ditwah, which devastated Sri Lanka, is now advancing toward the Tamil Nadu-Puducherry coast, bringing very heavy rainfall, gale-force winds and rough seas across the region. The system is forecast to run nearly parallel to the coast, making landfall unlikely, but causing major disruption in districts such as Nagapattinam, Cuddalore and the Puducherry–Karaikal region, all placed under red alert. Over 28 disaster-response teams from National Disaster Response Force (NDRF) and State Disaster Response Force (SDRF) have been activated, and flights and trains in and out of Chennai have been cancelled or diverted.

India has released a new earthquake map, putting the entire Himalayan region in the highest-risk Zone VI for the first time. The update shows 61% of the country is now in moderate to high hazard zones. Scientists say the Indian Plate pushes into the Eurasian Plate, building stress that can trigger major quakes. Long-unruptured faults in the Himalayas store huge energy, increasing risks. The map also reclassifies towns near fault lines, ensuring stricter building rules. Officials say this will guide safer construction, retrofitting, and disaster planning. Experts call it a major step for public safety. (PC: India Today)
